BURNER-TUBE CLEANER.

Specification of Letters Patent.- Patented'DGe 25', 1917- Application filed April 10, 1915. Serial No. 20,425." 7

To all whom it may concern Be it known that I, FRED H. MARRIOTT, a citizen of the United States, residing in VVatertown, county of Middlesex, and State of Massachusetts, have invented certain new and useful Improvements in Burner-Tube Cleaners, of which the following is a specification, reference being had to the drawings accompanying the same and forming a part thereof.

My invention relates to a device for cleaning the outlet in the burner feed tube of hydro-carbon burners.

The objects of my invention are to produce a cleaner for cleaning the outlet orifice in the burner feed tube of hydro-carbon burners by means of a needle so arranged that it will be guided into the outlet orifice of the burner feed tube.

Heretofore, to clean the small outlet orifice in a hydro-carbon burner feed tube it has been necessary to either remove the tip in which the outlet is located, or make a hook of wire and find the outlet by sense of feeling; or to remove a screw, which would permit a straight wire to be used. The reason that it is inconvenient to clean the tube in which the outlet is situated, by the old methods, is that the burner feed tube usually has its free end either just within the burner mixing tube or so close to it that the outlet cannot be seen by the operator, and to find the outlet has been a matter of sense of feelmg.

By the use of my device a guiding member is used which has a recess adapted to fit over the tapering free end of the burner tube to bring the axis of both in alinement. A cleaning needle is mounted with its free end in a central hole in the guiding member, which hole is so located as to guide the end of the cleaning needle into the outlet of the burner tube, the cleaning device being so arranged that it may be carried in the pocket, or any convenient place, and used at night when it is dark, as well as in the day time, and the outlet in the tube readily cleaned.

The necessity for cleaning this outlet arises from the fact that in vaporizing the fuel, such as gasolene, kerosene, and the like, specks of carbon form, as well as a tar residuum, and is carried by the vaporized fuel into the small outlet of the burner tube and lodged upon its Walls, which action gradually fills up the outlet,

fication and forming a part thereof- I Figure 1 represents a side view of my device, together with the burner feed tube and a section of a vaporizing pipe to which the In the drawings accompanying this speci ftube is attached so as to show the device in "the posltion in which it is used;

Fig. 2 is a sectional side view of a portion of my cleaning device and the burner tube designed to show the method by which the guiding member guides the cleaning needle into the outlet in said burner tube; and

Fig. 3 is an end section taken through line 33, Fig. 1, showing the form of the guiding member.

In the drawings, 1 represents the burner tube provided with the outlet orifice 2 for the fuel, located therein; 3 is a guiding member having a tapering recess 4 formed therein adapted to receive the tapering end of the burner tip. Holes 5, 5, are provided in the guiding member so as to permit of the escape of the hydro-carbon gas when the needle has cleared the outlet orifice 6 so that the hydrocarbon gas can escape. The guiding member 3 is provided with a central guiding hole to receive the cleaning needle 7, the hole being axially in alinement with the outlet 2 in the burner tube when the guiding member 3 fits over the tapering end of the tube, so that the point of the needle readily enters the outlet orifice 6. To slide the needle 7 back and forth, I provide the sliding-bar Shaving the needle 7 attached to alateral portion thereof, which sliding-bars is slidably mounted in a hole in the laterally extending portion 9 of the guiding member 3, the bar 8 having a straight stem 10 that freely slides in the lateral member 9. The handle 11 is provided so that the hand of the operator of the cleaning device can be carried away from the end of the mixing tube sufiiciently so as not to be burned by the hot gases.

A spring 12 is mounted upon the member 8, one end bearing against a fixed collar 13 and the other against the laterally projecting guiding member 9. This spring is provided to maintain the needle 7 in a non-operative position, as shown in Fig. 1, so that the needle will not interfere with the fitting of the guiding member 3 upon the tapering end of the tube 1. I

I do not confine myself to the exact form of device as herein shown, as the form and arrangement may be varied somewhat without departing from the oi my inyenr tion.

What I claim is A cleaning prising a guiding member formed to be detachably placed over the end of a;- bur-nevtube and having a guiding hole therein, a cleaning: need-lei having: one of itsends slid'-- ably mounted in said hole, a..hendle secured to the other end of said needle and having wwntr dep fi t e; a e lly xt n PM 911 n u ding mem n e ly mounted upon. the contracted. portionoff the handle, and a spinal spring. to; hold the dewiee ion tubes, coin-.2

needle in its normal position, the. Whole be- 15 ing arranged so as to cause the cleaning needle to aline with the hole in the burner tube-whenthelvni'ding. member is placed over the end of the burner tube.
